A model for railway crew allocation support system

The authors discuss a railway crew allocation problem and propose a model to support schedulers on the computer. They have developed a crew allocation support system which supports trial and error generation of crew service patterns by schedulers. Here they analyze the crew allocation problem for a certain company to build the basic problem structure. Next, they propose a conceptual framework, a four-layer gathering model, to support effective generation of service patterns to simulate the problem solving process of schedulers. The system finds the proper resource on each level and generates resources of the lower layer based on local constraints. Schedules can be created with less time and work
